Amateur Astronomers Discover 42 Alien Planets
A team of amateurs has discovered evidence for 42 alien planets, including a Jupiter-size world that could potentially be habitable, by sifting through data from a NASA spacecraft.
Forty volunteers with the crowd-sourcing Planet Hunters project discovered the new planet candidates, which include 15 potentially habitable worlds and PH2 b, a Jupiter-size planet that the team confirmed to be in the habitable zone of its parent star.
The planet PH2 b was found using data from NASA's prolific Kepler Space Telescope and confirmed with 99.9 percent confidence by observations at the W. M. Keck Observatory in Hawaii.
